FIG. 1 is a perspective view showing a rollable display according to an exemplary embodiment.FIG. 2 is a cross-sectional view of the rollable display according to an exemplary embodiment taken along line II-II ofFIG. 1 . - Referring to
FIGS. 1 and 2 , therollable display 100 includes aflexible display panel 130, a body member orhousing 110, arolling member 111, and aguide member 120. - The
flexible display panel 130 can emit light to display images. Theflexible display panel 130 is formed of a flexible material such as plastic to maintain its display performance even when it is bent like paper. - The
body member 110 has an internal space defined therein. The shape of thebody member 110 can be a pillar shape. In some embodiments, the shape of thebody member 110 is, for example, a substantially cylindrical shape. When the case has acylindrical body member 110 it may be easier to hold when compared to arectangular body member 100. However, the shape of thebody member 110 is not limited to a cylindrical shape. - The
rolling member 111 is rotatably positioned in thebody member 110. Therolling member 111 may be, for example, a roller. The roller can rotate around a shaft (not shown). - The
flexible display panel 130 is rolled around the rollingmember 111. The rollingmember 111 can have aconnection part 112 formed therein. Theconnection part 112 can be, for example, acircuit board 112. - The
circuit board 112 is formed so as to be accommodated in the rollingmember 111 and can have one end exposed from the rollingmember 111. Theflexible display panel 130 can be connected to the exposed portion of thecircuit board 112. Thecircuit board 112 can be electrically connected to theflexible display panel 130. Thecircuit board 112 can supply an image signal or power to theflexible display panel 130. - The
guide member 120 has a coil shape, is positioned in thebody member 110, and separates portions of theflexible display panel 130 such that they are not closely adhered to each other. That is, theguide member 120 can prevent overlapping portions of theflexible display panel 130 from directly contacting each other. - The
guide member 120 can be formed of a material that is not readily deformed, for example, a rigid material. Alternatively, theguide member 120 cam also be formed of a material that can be elastically deformed. In some embodiments, theguide member 120 is integrally formed with thebody member 110. In these embodiments, theguide member 120 can be formed of a material that is the same as that of thebody member 110. - Portions of the
flexible display panel 130 are positioned adjacent to each other by bending theflexible display panel 130 when theflexible display panel 130 is rolled around the rollingmember 111 or unrolled from the rollingmember 111. These portions of theflexible display panel 130 are spaced apart from each other by theguide member 120. As described above, theguide member 120 prevents the portions of theflexible display panel 130 from contacting each other. - The
guide member 120 can have a static electricity preventing coating layer (not shown) formed on a surface thereof that theflexible display panel 130 contacts. Friction can be generated between theflexible display panel 130 and theguide member 120 when theflexible display panel 130 is retracted into and/or drawn out from thebody member 110. However, generation of static electricity between theguide member 120 and theflexible display panel 130 can be prevented by the static electricity preventing coating layer. - When static electricity is generated, the frictional force between the
flexible display panel 130 and theguide member 120 increases. Therefore, a user needs to apply larger force when he/she draws out theflexible display panel 130 from thebody member 110. However, as described above, the generation of the static electricity can be prevented by the static electricity preventing coating layer, such that the user can smoothly draw out theflexible display panel 130 from thebody member 110 without using a relatively large force when drawing out theflexible display panel 130 from thebody member 110. - The above-mentioned static electricity preventing coating layer can be formed on the
guide member 120 by, for example, injecting a static electricity preventing solution onto theguide member 120, but is not limited thereto. - When the
rollable display 100 according to an exemplary embodiment configured in the structure as described above is not in use, since theflexible display panel 130 is accommodated in thebody member 110 such that theflexible display panel 130 is rolled around the rolling member, a user can easily carry the rollable display. Further, theflexible display panel 130 can be withdrawn from thebody member 110 to be used as a display device. -
FIG. 3 is a perspective view showing a flexible display panel which is withdrawn from a body member in the rollable display according to an exemplary embodiment shown inFIG. 1 .FIG. 4 is a plan view showing only the flexible display panel of the rollable display according to an exemplary embodiment shown inFIG. 3 .FIG. 5 is a cross-sectional view of the rollable display according to an exemplary embodiment taken along line III-III ofFIG. 3 . - Referring to
FIGS. 3 to 5 , therollable display 100 according to an exemplary embodiment further includes a knob member or handle 140. Theknob member 140 can have a stick or bar shape and is formed at one end of theflexible display panel 130. - When the
flexible display panel 130 is withdrawn from thebody member 110, theflexible display panel 130 can be easily handled via theknob member 140. Accordingly, a user does not need to directly contact theflexible display panel 130 in order to draw out theflexible display panel 130 from thebody member 110, and thus, it is possible to prevent the surface of theflexible display panel 130 from being marked with fingerprint(s) or other foreign materials. - In the
rollable display 100 according to an exemplary embodiment, thebody member 110 includes a slit part oropening 113 formed therein via which theflexible display panel 130 enters thebody member 110 or exits thebody member 110. In addition, therollable display 100 according to an exemplary embodiment can further include a foreign materialintroduction preventing member 150. The foreign materialintroduction preventing member 150 is formed along an edge of theslit part 113 and is positioned so as to be closely adhered to upper and lower surfaces of theflexible display panel 130. - When the
flexible display panel 130 is exposed to the environment, foreign materials can be attached to the surface of theflexible display panel 130. The foreign materialintroduction preventing member 150 removes the foreign materials from theflexible display panel 130 when theflexible display panel 130 is retracted into thebody member 110 through theslit part 113. To this end, the foreign materialintroduction preventing member 150 can be formed of one or more of the following: brush, cloth, and rubber. - Additionally, the structure of the
flexible display panel 130 described above can include adisplay area 131 and anon-display area 132. - An image can be displayed in the
display area 131. Thenon-display area 132 transfers signal(s) to thedisplay area 131. To this end, fine electrode patterns can be formed in thenon-display area 132. - In the
rollable display 100 according to an exemplary embodiment, thedisplay area 131 is positioned so as to correspond to theguide member 120 when theflexible display panel 130 is rolled around the rollingmember 111. In some embodiments, the length of theguide member 120 is substantially the same as the length of thedisplay area 131 of theflexible display panel 130. The end of thedisplay area 131 can be located adjacent to the end of theguide member 120 when theflexible display panel 120 is fully housed within thebody member 110. - One end of the
guide member 120 can be positioned adjacent to the rollingmember 111 and the other end thereof can be positioned adjacent to the slit part. One end of theguide member 120 can be positioned so as to be spaced apart from the rollingmember 111 by a predetermined distance. Thenon-display area 132 of theflexible display panel 130 can be rolled around the roiling member 111 a number of times. - The
rollable display 100 according to an exemplary embodiment configured in the above-mentioned structure further includes theguide member 120. Theguide member 120 enables portions of theflexible display panel 130 positioned adjacent to each other to be spaced apart from each other when theflexible display panel 130 is rolled around the rollingmember 111 or is unrolled from the rollingmember 111. Thus, the portions of theflexible display panel 130 are prevented from contacting each other by theguide member 120, thereby making it possible to prevent scratches from being generated on theflexible display panel 130 due to the foreign materials. - Additionally, the
rollable display 100 according to an exemplary embodiment can be a portable electronic apparatus such as a mobile phone, a smart phone, a tablet, an electronic book terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a digital broadcasting receiver, or the like. - While this disclosure has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
